Thread: How to handle COM Exception

hi guys ,

simple code to convert from text to speech .. it's supposed to work fine .
any way it generates a COM exception isn't handled .

Code:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
using SpeechLib;

namespace SimpTesTX
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            string s = "Hello World ";
            SpVoice sp = new SpVoice();
          
            sp.Speak(s, SpeechVoiceSpeakFlags.SVSFDefault);
           

       }
    }
}

thanx is advance .
